Application filed September 19, 1911. Serial No. 650.102.

To all whom it may concern:

Be it known that I, LYNN B. \Vrwrorr, citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specificavby which stencil plates or cards may be quickly introduced into the machine and properlypositioned to receive the first line of writing, and may be introduced into and fed through the machine in a flat condition.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, combinations of devices and arrangements of parts described in the following specification and particularly pointed out in the appended claims.

In the drawings wherein like reference characters indicate like parts in the various views, Figure 1 is a fragmentary, vertical, fore and aft sectional view, showing the upper portion of the typewriting machine ner posts 1 surmounted by a top plate 2.

Fixed oppositely grooved guide rails 3 are secured by screws 4 to brackets 5 fixed to the top platd. Anti-friction balls or rollers 6 are received in the grooved faces of the guide rails 3 and are also received in oppositely disposed grooved guide rails 7 of a guide bar 8 which constitutes the rear cross bar of the carriage. Forwardly projecting end bars 9 are connected to the cross bar 8 and form part of the carriage; said end bars being provided with hearings to receive a platen shaft 10 on which a rotative cylindrical platen 11 is mounted. Upwardly extending projections 12 are formed on the end bars 9 and are apcrtured to receive the ends of a cross bar 13 which extends throughout the-length of the platen above and to the rear of the center thereof. This bar is fixed to the projections 12 and constitutes a support for sleeve-like carriers 14. Each carrier is tapped to receive the threaded shank of a thumb screw 15. The end of each of the screws 15 is reduced, as indicated at 16, and is adapted to be received in a s line groove 17 which extends longitudinal y in the rod 13 throughout the len th thereof. It will be understood that by t iis arrangement the carriers are adapted to be connected against rotative movement on the rod 13 and are, nevertheless, capable of rela tive adjustment along the rod. Each carrier is provided with a socket which is parallel with the axis of the platen and is adapted to receive the off-set bent end 18 of a supporting arm 19. A set screw 20 is received in a tapped opening in each of the carriers 14 and bears at its inner end against the end 18. of the associated supporting arm 19. From an inspection of Fig. 1 it will be seen that the supporting arms 19 are substantially concentric with the platen and extend forwardly and downwardly from the supporting rod 13 to a point at the front of the platen where each arm is bentinwardly, as at 21, to form a bearing 22 for a feed roller 23. In the present instance each food roller is a me.- tallic roller with a knurled contact face or periphery 24, althmigh other suitable feed rollers may be employed. The bent. end 21 of each supporting arm 1!) is provided with a shoulder 25 against. which the associated feed roller bears at one side thereof.

At. the opposite side of the feed roller is arranged a washer so which is maintained in place against a shoulder 27 formed at.

' ingpoint, indicated at meet, to maintain the the periphery of the feed roller nearer to or farther rromv the platen, and that when the screw 20 is tightened the associated supporting arm 19 is secured against moveieed roller in the position to which it hasbeen adjusted relatively to the platen. The supporting arms 19 are rigid arms andt iey are thus rigidly supported to rigidly support the teed'rollers 23 in the positions to Which they may be adjusted toward or away from the platen.

A. platen scale 29 is arranged at the front of me platen. beneath the printing line and may be supported from. the carriage in the usual manner. I

A substantially horizontally disposed stationary "Worksheet supporting shelf or platform 30 is preferably formed as a part of depending arms 31 which are apertured to receive screws which extend through from the rear side of the usual depending front plate fixed in the usual. manner to the top plate oithe machine. The screws 32 may he fixed to the front plate 33 by any suitable means as by lock nuts 33. A thumb nut 34% cooperates with each. screw 32 to clamp the depending arms 31 to the forward face of the plate 83, thusfixedly securing the arms and the supporting shelf 30, which forms a part thereof, to the top plate an'dto the frame of the machine The porting shelf 30, as hereinb-efore in-' .dicated, is horizontally disposed and is arranged beneath ,tlie'printing line and at. the front of the platen and extends longitudinally of the platen at and near the center of the machine substantially parallel with the printing line; i 'l The sup orting shelf is provided with anupwaroly extending pointer 35 which is preferably form'ed integral therewith and projects toward and in line with the print- X in Fig. 2. From an inspection of Fig. l will be observed that the pointer is curved'in transverse section so that the side edges; thereof are bent-forwardly and do not form sharp edges or corners for contact with the stencil plate or card, designated as a. whole by thereterence numeral 36. From an inspection of the drawings it will be observed that. the pointer is arranged in front of the platen scale 29 and in a. position where a stencil.

plate may be inserted in the machine from the front of the platen and may pass between the pointer and the plat-en scale and supported at its lower edge on the sheltllnZQ support 30. The pointer, in addition to acting as such, to locate the printing point, also prevents. the lower edge of the stencil plate or card from being deflected forwardly and displaced from the supportshelrf 36". 'lfype 3? are pivoted 38 to type a, tee

har hangers 39, secured to' a segment 40. The type at their forward ends are supported on a type rest ii. The type bars may he act rated in the usual manner through pull links i2 and the types i3 may be of the usual construction or they may, if desired, he needle-faced types for puncturing thestencil sheet, although I prefer to employ type faces and to have the types, type bars and their actuating means of the usual construction such as. that employed in the Monarch machine. it will be oh served that the type bars strike upwardly and rearwardly against the front face of the platen, asindicaled by the dotted line in Fig. l.

lVhile the invention is intended primarily for preparing stencil. plates, in Wl'llCll-CHSQF the types strike directly against the face of the stencil sheet, it should be understood that the invention may be cmgloyed for filling in cards or the like and that in such instances the usual ribbon mechanism, which is omitted in the preparation of stencil plates, may be employed. The stencil sheet shown in the drawings is of the usual construction and comprises a thin sheet a and a pastebo'ard or a comparatively heavy paper frame or rim 2'). The margin feed rollers are oil-set inwardly from; the supporting arms 19, as shown in .l ig. 2, and cooperate with the end portions 'ot the "frame lflu'hich is usually thickerand more substantial than the stencil portion a of the plate. The arrangement of the parts is such that a stencil plate may be reacily introduced from above and supported upon the supporting shelf 30 in substantially a flat condition in the position shown in the drawings. in this osition the stencil plate is properly squared against the shelf and positioned to receive the first line of writ-- lug. There-are usually buttwo or three lines employed upon the stencil sheet and after the first line of the stencil is produced, the platen may he led. :foruard by the usual-line space mechanism, not shoen,

to feed the stencil plate upwardly the d. tance of one line space, when the sccoi l line may be produced. l Vhen the card is completed it is fed upwardly and Wit. drawn from the machine and a new stencil plate introduced downwardly as "before. 1

The construction, arranged in accordance with my present invention, is a simple one teat aitords a ready introduction and removal of the stencil sheet or card and a feed iii-g of the stencil sheet in the machine in a fiat condition and there is no ne cessity of efiecting a release of the feed ing devices in the introduction of the stencil sheets into or the removal thereof from the machine. The stencil sheets may he introduced into the machine by inserting them between the supporting l9 and emma between the feed rollers and platen, and by effecting a reverse or backward rotation of the platen the stencil sheet will be fed downwardly until the bottom sheet thereof is b ought into contact with the supporting shelf 30, which properly squares the sheet, and it is then in position to receive the impact of the types for the first line to be produced on the stencil sheet or plate.

Various changes may be made without departing from the spirit and scope of my invention.
